1. How can you tell which quadrant a point will fall in by looking at its coordinates?
Answer
You can tell it will land in the first quadrant if both the X and y coordinate are positive. You can tell it will land in the second quadrant if the X coordinate is positive and the Y is negative. It will land in the third quadrant if both the x and y coordinates are negative. If The x coordinate is positive and the y is negative it will land in the fourth quadrant.
example coordinates
2. You have looked at several problem situations in which you figured out how to make a able of data. You also learned that if you can write an equation to describe how variables are related, you can use a graphing calculator to graph the equation. How do you figure out what part of the graph makes sense in a real problem situation? Use an example to help explain. A. If you are buying items and are looking at a graph of their prices than you would look at the second quadrant. If you are looking at how much profit, a companies making than you would look at the third quadrant and you would look at the second quadrant.

Summary: This chapter was about working with graphing calculators on graphs and equations.
